摘　　要：针对青藏高原紫外线辐射强度高、温差大的特点,研究出一种抗光氧老化性能优良的雾封层道面养护材料。首先,比选了现有预养护材料耐光氧老化性能,其次研究了光固化剂种类及掺量对抗光氧老化性能的影响,最终优选出了一种光固化材料,并对其对抗紫外破坏能力进行了测试分析。微观测试结果表明,改性剂的加入,显著扼制了羰基的生成,使其具备较强的抵抗热氧和紫外线老化的能力,适合我国西部高原强紫外线地区使用。This project studied an anti-light aging fog seal coat materials under the Qinghai-Tibet Plateau special environmental conditions via adding the modifier in it.First,the light fastness aging properties of the existing fog seal coat pavement maintenance materials was contrasted.Then a variety of modifiers（curing agent） were chosen to modify the existing solvent asphalt fog seal coat materials,in addition,its light fastness aging properties was researched.Besides,the effects of the curing agent to the test results were studied.Finally,on the base of above research,a kind of resistant to UV aging fog seal coat maintenance materials were prepared,and its anti-aging properties were studied.The experimental results have shown that this fog seal coat maintenance material has a good resistance to UV aging and is suitable for the use of strong ultraviolet region of China＇s western highlands.
